摘要： A method of processing a biosignal includes estimating a time period from a time-domain biosignal, converting a biosignal corresponding to a time interval based on the time period to a frequency-domain signal, performing signal processing to remove a distortion component from the frequency-domain signal, and converting a processed frequency-domain signal obtained through the signal processing to a time-domain signal.

摘要： A signal feature extracting method and apparatus is disclosed. The signal feature extracting apparatus estimates element signals forming an input signal using a signal model to be determined by parameters, and extracts signal features using the estimated element signals. The method of extracting a signal feature including estimating element signals from an input signal, and extracting a signal feature using the estimated element signals, wherein the estimating of the element signals comprises estimating a first element signal of the input signal, and estimating a second element signal based on a waveform of a first intermediate signal, the first intermediate signal being a signal derived from the first element signal eliminated from the input signal.
